SAFETY
• Always wear flat-soled shoes when walking on the warming cable
• Do not place excessive weight (machinery, multiple tile packs) on the warming cable
• Do not place sharp objects or tools on the warming cable
• Cordon off the unfinished room to prevent unwanted access
2. Double layer of thinset mortar
• Suited to complex jobs
• May become a two-day installation
• Provides additional protection to the
warming cable when laying tiles
• Must prohibit access to the room while the first
layer is drying and before the second layer of
thinset cement is applied
1. Single layer of thinset mortar
• Ideal for small jobs
• Same-day installation
• Must be more careful when laying tiles
over the warming cable
TWO INSTALLATION METHODS
The cable has 4 layers
1. The twin heating wires are at the core
2. Teflon insulation surrounds the
heating wire conductors.
3. Braided sheath (to be grounded)
surrounds the two heating wires
4. Final layer of Teflon insulation
surrounds the braided sheath
CABLE CONSTRUCTION
AVOID HIGH PRESSURE POINTS
A High Pressure Point (HPP) is a force that tears open the Teflon layer which separates the core
heater wires from the ground sheath. This creates an electrical short and leaks electricity from the
core to the ground. A single HPP can be located even after the tile is placed, but several HPP’s
can generally NOT be located.

IMPORTANT: BEFORE STARTING YOUR FLOOR WARMING PROJECT, PLEASE REVIEW
THESE IMPORTANT INSTALLATION INSTRUCTIONS.
NEVER cut the blue warming cable*
NEVER shorten the warming roll*
NEVER connect TWO (2) warming rolls together in series, always wire in parallel
NEVER fold or position the warming system so that the mesh overlaps itself or other warming
cables (this could lead to dangerous overheating)
NEVER run a power lead or sensor wire across the blue warming cable
NEVER place built-in cabinets or furniture with solid, or enclosed bases on top of the heated
area of the floor
(this could lead to dangerous overheating)
NEVER when laying the system on top of a concrete subfloor, lay the warming cable over
an expansion joint
NEVER run a warming cable in or through a wall
NEVER lay the warming system closer than 2” from a wall or heat source
NEVER connect the warming roll to the power supply before it is installed beneath the floor
covering (this could lead to dangerous overheating)
NEVER operate the system until the mortar has had time to cure
*Cutting the warming cable or shortening the roll will:
1. Cause the installed warming system to overheat,
2. Take your installation out of compliance with the NEC (National Electrical Code) and UL
(Underwriters Laboratories), and
3. Require a correction effort that will cost you time and money. CAREFULLY CHECK YOUR
FLOOR PLAN NOW; CALL WARMLYYOURS at (800) 875-5285 if you need a different
length roll shipped overnight.
Note: You can cut and shorten the 15’ cold lead wire coming out of the warming roll.
